OROPHEA WILLlAMSil sp. nov. 
Arbor parva, plus minusve pubescentibus ; foliis oblongis, char- 
taceis, usque ad 17 cm longis, in siccitate supra pallidis, nitidis, 
apice distincte acuminatis, basi acutis vel subrotundatis, nervis 
utrinque circiter 10, subtus prominentibus ; floribus in fasiculis 
vel in umbellis breviter pedunculatis extra-axillaribus dispositis, 
pedicellis 1.5 ad 2 cm longis; petalis exterioribus ovatis, 8 mm 
longis; staminibus 12. 
A small tree, about 4 m high. Branches terete, slender, dark- 
colored when dry, glabrous, the branchlets ferruginous-pubescent. 
Leaves oblong, chartaceous, 11 to 17 cm long, 4 to 6 cm wide, the 
upper surface glabrous, pale and shining when dry, the lower 
somewhat brownish, duller, distinctly pubescent on the midrib 
and to a less degree on the lateral nerves, the base acute or 
somewhat rounded, the apex narrowed into a distinct, blunt 
acumen about 1 cm in length; lateral nerves about 10 on each 
side of the midrib, prominent on the lower surface, somewhat 
curved-ascending, distinctly anastomosing, the reticulations fine, 
subparallel, not prominent; petioles pubescent, 3 to 5 mm long. 
Flowers yellowish, in extra-axillary fascicles or in shortly pedun- 
cled umbels, 2 to 6 flowers in each. Pedicels prominently pubes- 
cent, 1.5 to 2 cm long, subtended by basal, lanceolate, acuminate, 
3.5 mm long bracts, each bearing a similar bracteole at about 
the lower one-third. Sepals broadly ovate, acuminate, pubescent, 
4 mm long. Outer three petals broadly ovate, pubescent, acute 
or obtuse, 8 mm long, 5 mm wide, nerved, the inner three of 
about the same length, the claw glabrous, 3 mm long, bearing an 
orbicular-reniform rounded limb which is pubescent on the back 
and glabrous on the inner face and distinctly horizontally sulcate 
or somewhat cucullate. Stamens 12, in two series, 1 to 1.2 mm 
long. Carpels about 5, densely pubescent, narrowly ovoid, 2 mm 
long, somewhat curved, each with about 6 ovules, apparently 
borne in two rows. 
Mindanao, District of Zamboanga, Sax River, R. S. Williams 2311, 
February 26, 1905, in forests, altitude about 200 meters. 
A species manifestly allied to Orophea villamilii Merr., but with dif- 
ferently shaped, rather prominently acuminate leaves, more numerous, 
longer pedicelled flowers, and entirely differently shaped inner petals which 
are glabrous within and horizontally sulcate or cucullate.
